Martin Scorsese is a director who likes to have muses, but it seems Leonardo DiCaprio may see the famed director as his muse, as he’s brought the helmer in to direct one of his passion project, and adaptation of Erik Larson’s true-crime thriller, The Devil In The White City, according to Deadline.

Leo has long wanted to bring the book to the screen, but even with his backing it’s been a tough sell, but with Scorsese also backing it, it’s finally got some traction, with Paramount winning a major bidding battle to take on the movie.

In the movie, ‘DiCaprio will play one of the most prolific serial killers in Chicago history, the 19th century equivalent of Hannibal Lecter.’ He would be the legendary Dr H.H. Holmes, a man who has already inspired many movie characters and is most famed for his ‘murder castle’, a hotel he had built complete with secret passages, tube and various contraption which allowed him to kill people at his leisure.

The Imitation Game’s Graham Moore will write the script, although it’s not clear when it might shoot.
